------解决方案--------------------
declare @message varchar(50)

set @message = '0755 '

--左模糊匹配

select * from AutoReply_DestCodeFilter where left(DestCode,Len(@message)) = @message and FetchMethod = 1 union all

--右模糊匹配
select * from AutoReply_DestCodeFilter where Right(DestCode,Len(@message)) = @message and FetchMethod = 2 union all

--任意匹配
select * from AutoReply_DestCodeFilter where DestCode like '%0755% ' and FetchMethod = 3
------解决方案--------------------
select * from AutoReply_DestCodeFilter where charindex(@message,DestCode )> 0
------解决方案--------------------
select * from AutoReply_DestCodeFilter where left(DestCode,Len(@message)) = @message and FetchMethod = 1 or Right(DestCode,Len(@message)) = @message and FetchMethod = 2 or DestCode like '%0755% ' and FetchMethod = 3
------解决方案--------------------
--try

select * from AutoReply_DestCodeFilter
where DestCode like
case FetchMethod
when 1 then '0755% '
when 2 then '%0755 '
when 3 then '%0755% '
else '%%% '
end
